This feature provides support for call suspend and resume services initiated by ISDN BRI phones connected to the device. During an ongoing call, the BRI phone user can suspend the call by typically pressing the phone’s “P” button or a sequence of buttons (depending on the phone) and then on-hooking the handset. To resume the call, the phone user typically presses the same button(s) again and then off-hooks the phone. During the suspended state, the device plays a Howler tone to the remote party.

Note that instead of pressing the call park button(s), the phone cable can also be disconnected (suspending the call) and then reconnected again (resuming the call).

If the phone user does not resume the call within a user-defined interval (configured using the existing HeldTimeout parameter), the device releases the call.
